Terms Useful in Working With E-Records: Artificial Intelligence (AI) – field of computer science that deals with the development of systems that mimic human intelligence such as problem solving Automatic indexing – the automated selection of key words from a document in order to develop index entries (also see Classifying) Backfile conversion – the process of identifying, indexing, coding, and/or inputting a large volume or backlog of documents into a recordkeeping system Backup – the process of duplicating information, primarily for protection against damage or loss (i.e. backup tapes) Bar code – a coding system of vertical lines or bars set in a predetermined pattern that, when read by an optical reader, can be converted to machine-readable language. Bit – the smallest unit of information recognized by a computer 8 bits = 1 byte 1,024 bytes = 1K (kilobyte) 1,000 K = 1MB (megabyte) (1,048,576 bytes) 1,000MB = 1GB aka 1GIG (gigabyte) (1,073,741,824 bytes) 1,000GB = 1TR (terabyte) (one trillion bytes) 1,000TR = 1PB (petabyte) (one quadrillion bytes) FYI – a terabyte or more of storage space has become possible for personal computers – cost of TR of memory in 2005, $450; down from $1,000 in 2003 Bit-mapped image file – a computer processible file that encodes images as patterns of dots - often referred to as raster graphics Classifying – the act of analyzing and determining the subject content of a document and then selecting the subject category under which it will be filed. (Some new RM software systems have the capability to “auto classify” documents based on key words.) Cold site – an unfurnished space suitable for the installation of computer and communications equipment. An alternative facility that is void of any resources or equipment, except air- conditioning and raised flooring that can be used as a backup site for disaster recovery Compact disk-read-only memory (CD-ROM) – a read-only optical disk format for computer- processible information Compact disk-recordable (CD-R) – a write-once optical disk in the compact disk format (write once, read many) Compact disk-rewritable (CD-RW) – an erasable/rewritable optical disk in the compact disk format Data – groups of characters that represent a specific value or condition, data provides the building blocks of information (see also Metadata) Data archiving – the process of transferring electronic records from on-line storage devices, such as hard drives, to removable recording media, such as magnetic tape or optical disks, for off-line storage. In most cases, the archived data is relatively inactive and does not need to be accessible on-line. Data compression – techniques implemented through computer programs that reduce the amount of storage space required for a given quantity of information. Database – a collection of related data stored on a computer system that can be manipulated or extracted for use with various applications but managed independently of them Digital audio tape (DAT) – a four-millimeter magnetic tape format utilized for audio or data recording Digital coding – a coding scheme that represents information by predetermined sequences of bits. Electronic records created by computer systems employ digital coding, as do certain audio and video records. Digital linear tape (DLT) – a high-capacity recording media that uses half-inch magnetic tape enclosed in a plastic cartridge (frequently used in storing seismic data, 100 regular tapes can fit on 1 DLT) Direct-access storage device (DASD) – a hard disk drive in a large computer installation Document management (DM) – a management control system used to regulate the creation, use and maintenance of electronically created documents. Also referred to as EDMS – electronic document management system Dots per inch (dpi) – the most common measure recording density/resolution of images in computer systems. (When used in scanning paper documents 200 dpi and 300 dpi most often preferred.) Drawing interchange format (DXF) – a file format used in computer aided (CAD) design programs Electronic data interchange (EDI) – a standardized method of electronically transmitting and processing data from one computer to another EDMS – electronic document management system Electronic record – a record that contains machine-readable, as opposed to human-readable, information Electronic records management (ERM) - applying records management principles to electronic records that are located on disks, tapes, or any form of magnetic or optical media Encryption – any procedure used prevent anyone except the intended recipient from reading the data. There are many types of data encryption that are the basis of network security. Fat Client – see Thick Client Field – space allocated for a particular item of information. The smallest unit of information within a database record. In database management, a required field is one in which you must enter data, while an optional field is one you may leave blank. File – a general term that denotes a collection of records File transfer protocol (FTP) – a client-server protocol that allows a user on one computer to transfer files to and from another computer over a TCP/IP network (transmission control protocol) Fixed magnetic disk drive – a magnetic disk drive with nonremovable, rigid platters. It is the most common type of hard disk drive. Floppy disk – a platter-shaped magnetic recording medium with a flexible substrate; also known as a diskette, it can be removed from a disk drive Full – text search – the ability of a system to search text files for specific words, digits, sentences, or set patterns (strings) of characters Graphic interchange format (GIF) – a widely utilized format for computer images in Internet, intranet and extranet implementations. It supports color and various resolutions, very effective with scanned images. Hard disk – a type of magnetic disk on which you can store computer data. Hard disks are the storage media of choice in high-performance computing applications. Hard disks may be fixed or removable. Hard drive – a magnetic disk mechanism that reads and writes data on a hard disk. Hardware – equipment or physical devices used to store or process data Hierarchical index – an index based on an orderly relationship of items where the most important items or topics are identified and subdivided into more specific categories Hierarchical storage management (HSM) – a data storage management strategy in which special software is used to separate active and inactive computer data by migrating files between primary and secondary storage media Hit – term used to indicate an answer located by an electronic system that seems to meet or match the search parameters Hot site – a fully equipped, standby computing facility available to subscribers for emergency use on short notice. An alternative facility that has the equipment and resources to recover the business functions affected by the occurrence of a disaster Hypertext markup language (HTML) – a mark-up language used for formatting information on the Internet and in intranets and extranets Image file – a file containing computer-processible images Imaging – the process of capturing information electronically (by scanning) from paper or microform Interface – a device or program that permits one part of a computer system to work with another JPEG – an image compression method developed by the Joint Photographic Experts Group Jukebox – a robotic retrieval unit that provides unattended access to information recorded on optical disks or magnetic tapes; also known as an autochanger. A storage device that holds optical disks or tapes and has one or more drives that provide automatic on-line access to the information contained therein Key field – a field selected for indexing records contained in a database Keyword – a word or phrase taken from the title or text of a document characterizing its content and facilitating its retrieval Local area network (LAN) – a data communication network intended to allow several computers, connected through one computer to share data and software Magnetic card – an obsolete, rectangular medium coated with a magnetizable recording material Magnetic disk – a platter-shaped substrate coated with a magnetizable recording material Magnetic tape – a thin ribbon or strip of polyester coated with a magnitizable recording material; it may be wound on a reel or packaged into a cartridge or cassette Metadata - information about a particular data set that may describe, for example, how, when, and by whom it was received, created, accessed, and/or modified and how it is formatted. Some metadata, such as file dates and sizes, can easily be seen by users; other metadata can be hidden or embedded and unavailable to computer users who are not technically adept. Metadata is generally not reproduced in full form when a document is printed. ...
